After pressing process, there are many impurities in the crude palm oil, which might have bad influence on the oil’s sensory and edible qualities. Therefore, it is necessary to refine the crude oil. The main componentof crude oil: Mixed fatty acidtriglycerides, commonly known as the neutraloil. Phospholipids, free fatty acids, pigments, peroxides, waxes and various mechanical impurities.

The presence of these impurities is bad for taste , processed and it’s bad for the storage of edible oils.

How to refine the oil?

The main processing of 50T/Dricebranoilrefinery machine

1. Crude oil

2. Degumming

3. Deacidification

4. Bleaching

5. Frame filter

6. Deodorization

7. Dewaxing

8. Leaf filter

Detailed step

(1)Pump crude oil into refining tank and heat with conduction oil, and the temperature will reach about 70°C-80°C after one hour. Add acid or alkali to separate according to the acid value. After one hour's processing and 4-6 hours deposit, then convey soap stock to storage tank.

(2)Pump refined oil into decoloring tank. When it is up to 90-110°c after one hour's heating,

add clay into tank for 20min's processing. Then separate clay and oil with filter.
